Woodcut illustration from Der gantzen Artzenei, 1542. Johann Dryander (Eichmann) (June 27, 1500 - December 20, 1560) was a German anatomist, astronomer and physician. In 1535, he was appointed professor of medicine at the University of Marburg. Dryander was one of the first textbook authors to illustrate with woodcuts and the first to illustrate a Galenic dissection of the human brain. An expanded edition of this early book, the Anatomiae pars prior, was published in 1537. As an astronomer, Dryander emerged as the author of much-used textbooks describing and using astronomical instruments. In 1538, he published his major astronomical work Astrolabii canons brevissimi. In 1542, he published a translated edition of Mundinus' anatomy. He continued to write on medical subjects as well as mathematics and astrology until his death in 1560 at the age of 60. NOTE: Dryander is a family name. It originates as a 16th century name, literally meaning, oak-man. It was used by people whose original name was Eichmann (oak-man), Eichholz (oak-wood), de Enzinas (of the holm-oaks) etc.
